Appeal No. 2001-1211
Application No. 09/070,580
Upon a review of Hashimoto, we agree with Appellants that
the reference fails to teach either the position means that
includes a demodulator, a digital signal processor and a memory
in addition to a coil and a coil driver or a structure that
differs only insubstantially from Appellants’ structure. The
servo system of Hashimoto accelerates the head by adjusting the
gain according to the values in a gain setting table (col. 5,
line 59 through col. 6, line 2) to provide the detection gains
suitable for the difference between a specified track position
and the current track position (col. 8, lines 27-46). This
arrangement differs substantially from the structure in
Appellants’ disclosure that corresponds to the claimed “position
means” for positioning the head. As discussed above, Appellants’
servo circuit uses the programming in memory 150 to obtain a
continuously updated servo gain that adapts to incurring changes.
The subject matter of claim 8 would not, therefore, have been
prima facie anticipated by Hashimoto. Accordingly, we do not
sustain the rejection of claim 8.
